Evaluate the expression $\frac{2 a 鈭� b^{2}}{a b} + \frac{c 鈭� a}{b^{2}}$ if $a = 8, 鈥夆赌� b = 4, c = 16$ .

Short Answer

Expert verified

The value of the expression of $\frac{2 a 鈭� b^{2}}{a b} + \frac{c 鈭� a}{b^{2}}$ is $\frac{1}{2}$ .

Step by step solution

Step 1. Apply the BODMAS rule.

According to the BODMAS rule of simplification, at first, the bracket operation must be completed followed division, by multiplication, addition, and finally subtraction.

Step 2. Example of applying BODMAS rule.

The expression $5 b 鈭� \frac{2 a}{c}$ where $a = 3, 鈥夆赌� b = 4, 鈥� c = 2$ can be written as

$\begin{array}{l} 5 b 鈭� \frac{2 a}{c} = 5 (4) 鈭� \frac{2 (3)}{2} \\ 鈥夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€� = (5 脳 4) 鈭� \frac{(2 脳 3)}{2} \\ 鈥夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€� = 20 鈭� 3 \\ 鈥夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€夆赌夆€� = 17 \end{array}$

Step 3. Description of step.

Substituting $a = 8, b = 4 andc = 16$ in $\frac{2 a 鈭� b^{2}}{a b} + \frac{c 鈭� a}{b^{2}}$

$\begin{array}{l} = \frac{2 a 鈭� b^{2}}{a b} + \frac{c 鈭� a}{b^{2}} \\ = \frac{2 (8) 鈭� {(4)}^{2}}{(8) (4)} + \frac{(16) 鈭� (8)}{{(4)}^{2}} \\ = \frac{16 鈭� 16}{32} + \frac{8}{16} \\ = 0 + \frac{8}{8 脳 2} \\ = \frac{1}{2} \end{array}$
